Hi,

 

According to page 15, points 7-8-9, on the following document

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/elmuserguide/9_1_1/license_migration/CUCM_BK_CBF8B56A_00_cucm-license-upgrade-guide.pdf

 

You are required to re-install the complete cluster after upgrading to 9.1(1) and taking a DRS backup.

 

Is this really neccesairy? This would cause a tremendous downtime period.


Can someone please confirm or inform me otherwise?


Regards,

Erik Tamminga
